Research Description:
Our laboratory studies B lymphocyte development. We discovered a B cell-intrinsic locus, Bcmd-1 (B cell maturation defect), that regulates the peripheral B lymphocyte life span. When Bcmd-1 is mutated, peripheral B lymphocytes die prematurely, rendering the animal profoundly B cell deficient and incapable of producing memory antibody responses. Current genetic experiments are mapping Bcmd-1 and constructing a congenic strain for future in vivo studies of Bcmd-1 function. A candidate locus is under investigation. Current biochemical experiments are testing growth factor receptor signal transduction pathways and the synthesis of apoptosis inhibitory proteins in wild-type and Bcmd-1-mutant B cells, with the goal of identifying the biochemical pathway that is disrupted by the Bcmd-1 mutation.
